Abstract

INTRODUCTION: It has been generally accepted that exercise involving unaccustomed eccentric contraction results in micro muscle damage leading to a so-called delayed onset of muscle soreness (DOMS). Considering that the extent of micro muscle damage be different when the exercise is performed in different muscle length (short vs. long), based on the “popping” sarcomeres theory (Morgan, 1999), this study aimed to test the effect of muscle length of eccentric exercise on the shape of torque-angle relationship.
